how can I know how many lamps do I need? It's going to be a rectangular pool of 11.5 ft x 16.4 ft and 4 ft tall (water level)

1 is more than enough. I have a larger kidney shape pool and it looks like vegas.

We use one for our pool and the smaller one is for the spa. Our pool is quite large and one light is more than sufficient. Hope that helps.

One large pool light will be fine! My pool is 33ft long by 18ft wide and 4 to 8ft deep. One light does really well

I would get 2 of these kits for a total of 4 panels. My pool is 6500gals and one kit heats it perfect

I have a 110 4ft by 3ft i bought two of them. You can't go wrong. They are a great light.

since they are only 1 watt each-you need a very small transformer. If you are planning to add additional lighting especially flood lights non-LED you will need to make sure your get one to be large enough to meet your current + future needs.

Save your money and buy lumatek. Apollo is junk. On average, you will need 50 watts of light for every square foot of floor space that you want to grow on. If your space is 10 x 7 (70 square feet) you will need 3,500 watts. If your floor space is 10 by five you will need 2500 watts. Spend some money on ventilation as those lights get very hot and will fry your plants. Lumatec has a ballast that will fire 400, 600, and 1000 watt lights which allows you the flexibility of changing your garden according to different lighting requirements.

Hi Yunping-An accurate measurement would be lumens per square meter which is an industry standard. A Philips 500W reflector pool bulb designed for 120-130V operation is rated at 5000 lumens. Our PoolBright202 has various light outputs, from 1075 lumens to 11850 lumens, depending upon which color is displayed. W=11850; Y=10700; G=8600; AQ=8600; V=3550; R=2150; B=1075.

take the capacity of your transformer in watts, then the length of the pathway to determine the watts per foot, then work out the spacing based on the bulb wattage you have and/ or the number of lights you need without over loading the transformer

The 12 watt will probably not meet your needs if you have coral, but 2 would probably light most of your tank for visual purposes. I am guessing that you could only fit 3 over the surface area of the water. Depending on how high you hang them above your tank I am guessing 2 or 3 of the higher watt bulbs (I have a 54watt on my refuguim and my colt corals are thriving there) would support some corals.If you are using a Bio-cube hood these will not fit under it.

I thought the same thing. The unit is only 44 W. The picture is a different unit. I run a 20 w spot lamp and 5 4w lamps

You will probably need more then one. I have a 18 by 48 pool and it works but I think 2 would be better.

I have a 100 gallon cylindrical tank 18" x 72 " works fine very good lights, even illumination, intensity adjustable, can do white, or blue light or combination, and moon light

It really depens on how ong it will be before you can water the plants again. I use one large for each pot and some of the pots are 12" wide. If I was going for more then 4 days then I use 2 bulbs. We live in NM with little rain.

The closest would be an 11 watt but the lamp is physically larger, 1-3/4" as compared to 1-3/8". Also it would be twice as long. Feel free to call 317-782-8362 if you have additional question. John

traditionally, the lights are rectangle - but, if the light can cover the pool table envenly then it should be fine. We haven't installed our yet. It is nice though.

I purchased a 9' x 18' retangular pool. You wil need to add 2' to each side minimum. I purchase a screen cover for my pool. It keeps all the insects and trash out. That is the key to low maintance.

Hard to answer but I suspect 4 would be adequate. Keeping in mind it sounds like you have fluorescent tube lights and these are not tubes nor fluorescent. Four of these lights will be more than enough to light a 20' x 20' room though.

Depends on what you have in the tank and the length. 4 foot wide fish only two 24" light pack will do. If you have coral you would probly want 4 24" minimum. High lighting coral need 3-4 watts per gallon. Most coral 2-3 watts per gallon will do.
